Procurement Notes

Verify RoHS compliance status as datasheets indicate lead-free variants exist for this part number. Confirm the specific suffix 'I' denotes the industrial temperature grade. Check current manufacturing status, as older CPLD families may have end-of-life implications or require obsolescence management strategies for long-term production runs.

Selection Notes

Select this model when 256 macrocells are sufficient for the design requirements. Ensure the PCB layout accommodates the 256-pin FBGA footprint. Verify that the 3V-3.6V VCCIO/VCCINT supply rails match the target system power architecture. Consider the 9 ns delay constraint for high-speed synchronous interfaces.

Part Context

This component belongs to the AMD CoolRunner XPLA3 family, which bridges the gap between complex GALs and FPGAs. It utilizes CMOS technology for low power consumption while maintaining non-volatile configuration storage. The series is designed for cost-sensitive applications needing reprogrammability without the complexity of FPGA routing resources.

Replacement Considerations

Publicly confirmed substitute part numbers include XC2C256-7FTG256C from AMD.
